7z is an open archive format that usually achieves noticeably higher compression than ZIP or RAR, thanks to the LZMA and LZMA2 algorithms. It supports AES-256 encryption of both file contents and file names, handles archives up to 16 exabytes, and can split output into volumes. The specification is published openly, with no licensing restrictions on implementing it.
How to open a 7z file?
7z archives are created and read by 7-Zip, which remains the reference application for the format. Once it is present, a 7z archive opens with a double-click.
On macOS, The Unarchiver or Keka handle 7z, and on Linux the p7zip package provides the same functionality from the command line. WinRAR and PeaZip can also extract 7z. Because the strongest compression settings are slow and memory-hungry, very large 7z archives take a while to unpack. You can also convert the file with our 7Z to ZIP tool.
